Sub-sieve KClO4 and atomized Al powders, commercially classified into fine, medium and coarse fractions, were blended in 6040 KClO4Al compositions, loaded into plastic Titan cartridge cases, and tested for luminosity characteristics at sea level and a simulated ALTITUDE OF 80,000 FEET. Those systems containing fine 0-12 micron, medium 0-23 micron, and coarse 6-85 micron KClO4 together with fine Al 0-17 micron were the only systems which emitted enough light for pyrotechnic applications. Maintaining the aluminum particle size constant fine fraction and decreasing the oxidant particle size increased efficiency candlesecondsgram at both sea level and 80,000 feet. In general, the peak and integral light varied similarly at high altitude. At sea level, however, the composition with the coarse oxidant fraction produced the highest peak and integral light.
